My great Aunt Mabel Jackson married Mervyn in the UK in 1918. They returned to Canada in 1919 with their son Joseph Mervyn Dutton. I am not sure whether they returned to Russell, Manitoba, or to Calgary. Family memory suggests that Mabel died in child birth prior to 1930. Did she die while giving birth to Mervyn's second son Thomas Alexander in 1923, or at some point before or after. I would like to establish when she died and when Mervyn married his second wife Phyllis (nee wright), and I am finding hints of a third wife Mary? Can anyone help?
